Scandinavian Airlines (SAS) joined the SkyTeam alliance last year, and now it’s getting closer to the biggest airline in the group, Delta. After signing a codeshare agreement last year, SAS and Delta Air Lines are expanding their partnership with more codeshare flights.

Let’s take a look at what the latest news means for travelers.

What’s in the Delta and SAS Codeshare Agreement

SAS left Star Alliance last year and joined rival alliance SkyTeam on September 1, 2024. For U.S. travelers, this was important because Scandinavian Airlines — the flag carrier of Denmark, Norway, and Sweden — would leave the alliance where United Airlines also is and join the one where Delta is the North American anchor.

On September 25, 2024, Delta Air Lines and SAS also began a codeshare agreement. That’s a business arrangement in which airlines publish and market the same flight under their own airline designator and flight number, as part of their published timetable or schedule.

The practical offshoot is that travelers can start on Delta flights and then connect onward to an SAS flight, providing access to additional destinations, on a single booking. The same holds true in reverse. So we have Delta flight numbers and marketing on SAS flights, and SAS marketing Delta flights on its own website.

Now, starting April 2, the codeshare partnership is being expanded, with more destinations and increased frequencies between the U.S. and the 3 SAS hubs across Scandinavia in Copenhagen (CPH), Oslo (OSL), and Stockholm (ARN).

SAS said on its site that the codeshare expansion from Copenhagen includes 21 weekly departures to New York (JFK) and Newark (EWR) airports and 10 to Minneapolis (MSP). From Stockholm, departures to New York (also JFK and EWR) will increase by 20 flights per week. SAS also previously announced new flight routes to the U.S. for the summer of 2025.

SAS is listed as a Global Airline Partner on the Delta site, meaning SkyMiles members can earn miles and Medallion Qualification Dollars on all SAS flights, even those that are not codeshares. Conversely, members of the SAS Eurobonus program can earn points on all Delta flights.

SkyTeam partners have also published award charts covering redemption flights on SAS.

Delta and Scandinavian also now have reciprocal elite benefits. If you hold Medallion status with Delta, your benefits — for example priority check-in, increased baggage allowance, and lounge access — will carry over when flying SAS.

Final Thoughts

Scandinavian Airlines, or SAS, was a founding member of Star Alliance, way back in 1997 when the first — and still largest — airline alliance was formed. Now that it has changed sides and joined rival SkyTeam, it has become closely integrated with the biggest carrier in SkyTeam, Delta.

This is great news for U.S. flyers headed to Northern Europe, where SAS, although a relatively small airline, has a big footprint. The expansion of the codeshare agreement with Delta beginning in April is a further step in the Delta/SAS cooperation, especially benefiting loyal flyers with both carriers.
